含砷低品位氧化金矿石柱浸研究

Study on Column Leaching of As_bearing and Low_grade Gold Oxide Ores

摘要: 低品位复杂氧化金矿, 因其品位 < 3g/t, 只适合“堆浸”生产, 而堆浸过程中主要需解决其氰化率低的关键问题, 本试验为了提高其氰化率而采用试剂预处理, 使氰化率提高到83 %~ 91%。

Abstract: The grade low-of complex grade gold oxide ores are less than 3g/t, this kind of ores are fit for leaching only.The key problem that must be solved in leaching is the low rate of cyaniding.In this test, the agents are pre-processed, and the rate of cyaniding is risen to 83%~91 %.
